I have seen some information about EISA disk controllers.  Apparently,
this disk controllers can provide transfer rates that are substantially
higher than anything that PC's have had before.  Austin Computer Systems
has an EISA controller for their 486 machine which, they claim, can
transfer at rates up to 33 MB/sec (the key words there being "up to").

Does anyone know the scoop about these controllers?  Specifically, how
fast can they write to disk in a _continuous_ mode.  We are interested
in extremely fast disk transfers for some image processing that we
will be doing.  Ideally, we would like to be able to handle 8 MB/sec
transfers.  This would allow us to record video images in real time
from a digitizer without use of a VCR.  However, if we can get
4 MB/sec, we may be content with that.

Thanks.
